How can I change coloring of the binscatter by graphs?

[John Williamss]

I know we can generate overlayed binscatters with binscatter y x , by(group) . The problem is that the colors are very close to each other (especially for the color blinded people). Is it possible to change group colors?

[Scott Merryman]

There are -color()-, -mcolor()-, and -lcolor()- options:

sysuse auto,clear
